Networking Fundamentals — Question 49

What are three advantages of VLANs? (Choose three.)

Answer options

• A. They can logically address packets by using IP.
• B. They require a router to connect to VLANs on another switch.
• C. They compartmentalize a network and isolate traffic.
• D. They are efficient because a single switch can implement only a single VLAN.
• E. They act as though they are on the same LAN regardless of physical location.

Correct answer: B, C, E

Explanation

The correct answers B, C, and E highlight that VLANs require a router for inter-switch communication, effectively isolate network traffic for security, and allow devices to communicate as if on the same LAN despite being physically separated. Option A is incorrect as VLANs do not directly address packets using IP, and option D is false because a switch can support multiple VLANs, not just one.
